Abstract
A fountain applicator handle is disclosed for providing a continuous supply of a liquid coating to an applicator head for application onto a surface. The fountain applicator handle includes an elongated hollow reservoir with a sliding displacement piston disposed therein. A valve body is attached thereto and adapted for attachment to a coating supply, with the valve body allowing the communication of the coating into the reservoir while preventing the outflow of the coating to the applicator, and controllably communicating the coating from the reservoir to the applicator. Specifically, a fill tube is insertable through a check valve and sealable in a tapered segment in the fill channel of the valve body. In the most preferred form, the check valve is biased in a closed position independent of back pressure of the liquid coating. Particularly, in the most preferred embodiment, the plates of the check valve intersect with the inner surface of a cylindrical shroud, with ribs formed on the outer surface of the cylindrical shroud being press fit in the fill channel for preloading the plates together.
